Introduction

Write a MySQL query to update the Branch number in the stuents table, where firstname = John. I have used phpMyAdmin for the following Exercises.

StudentId	FirstName	LastName	Admission_fee	Admission_date	Branch	Branch_ID
1	John	Smith	1000	2018-06-10	Computer Engineering	111
2	David	Jones	1200	2018-06-20	Civil Engineering	222
3	Michael	Johnson	900	2018-08-15	Chemical Engineering	333
4	Chris	Lee	1500	2018-07-10	Electrical Engineering	444
5	Mike	Brown	1600	2018-09-10	Mechanical Engineering	555
6	Lisa	Smith	1800	2018-07-10	Computer Engineering	666
7	Mary	Smith	1600	2018-06-11	Computer Engineering	777

UPDATE students
SET branch_id= REPLACE(branch_id, '111', '1111') 
WHERE firstname LIKE '%John%';
